It is alleged that, in May and June 2008, Mr Hill sent several copies of a DVD entitled 7/7 Ripple Effect to the judge and the foreman of a jury at the trial at Kingston Crown Court of people allegedly involved in assisting the 2005 bombings.

7/7 Ripple Effect is a film, available on the internet, which claims people accused of involvement in the bombings are innocent and that the bombings were an “inside job”, perhaps involving state intelligence agencies in either Britain or Israel.

The British authorities claim copies of the DVD were sent, in packaging with Irish postal marks, between September 2007 and December 2007 to five relatives of people who had been killed during the bombing.

In court yesterday, Sgt Seán Fallon said that when arrested at his Kells home at 8.14am, Mr Hill, when asked about the DVD, had said: “I sent it. I believe those men to be innocent.”
